An effective method of power management in DC nanogrid for building application

Nanogrids are part of a microgrid which is powering a single house. Low voltage DC distribution within house structures is called a DC nanogrid. DC electronic loads like BLDC fans, Laptop, LED Lights, battery management system and renewable sources can be connected to the nanogrid. DC nanogrid is a low power dc distribution system suitable for residential applications. The objective of the work is to investigate the power and control architecture, to implement DC Nanogrid for building applications. Protocol for Nanogrid communication is based on ZigBee IEEE 802.15.4 and CANopen standard (EN 50325-4). Control strategies for effective power management in Nanogrid is highlighted in this work.
